ObjectivesTo conduct a survey of mass-specific inherent optical properties in coastal waters, using in situ measurements of absorption, beam attenuation and forward scattering, and an indirect method to determine the volume scattering function. The results of the survey are to be used to evaluate the effect of strong variations in the optically dominant class of suspended particles on marine reflectance. The objective of this particular cruise was to make measurements of the mass-specific optical properties in sediment dominant water (i.e. the Irish Sea) and determine how inorganic sediment affects marine reflectance.
A secondary objective of this particular cruise was to take grab samples along a transect from northwest Anglesey into the western Irish Sea. These grab samples are to form the basis of a final year student project. The project is examining changes in Formanifera sp along the transect to see if the species type and distribution changes across the western Irish Sea front.
